I had a terrible first impression with Gemini CLI a few months ago when it was released because of the constant 409 errors.

With Gemini 3 release I decided to give it another go, and now the error changed to: "You've reached the daily limit with this model", even though I have an API key with billing set up. It wouldn't let me even try Gemini 3 and even after switching to Gemini 2.5 it would still throw this error after a few messages.

Google might have the best LLMs, but its agentic coding experience leaves a lot to be desired.
